Abstract
651,117. Making turbine blades. PACKARD MOTOR CAR CO. Nov. 29, 1948, No. 30951. Convention date, Dec. 10, 1947. [Class 83 (ii)] A gas-turbine blade is made from a strip 13 of uniform thickness by removing metal from one face thereof, except along its longitudinal edges 15, in order to provide a varying thickness substantially throughout the full length of the strip, folding the strip about a longitudinal line and shaping it, welding together the longitudinal edges of the strip and removing metal 16 from the welded joint to form the desired edge contour. Metal is preferably milled from one surface of the strip 13, Fig. 4, from a point at or' adjacent one end to the other end so as to produce a wall whose thickness decreases gradually. The strip is then formed around a mandrel 17, Fig. 5, and, after being removed therefrom, has its free longitudinal edges joined by a continuous, spot, or stitch electric-resistance, weld. The seamed edges of the strip are then ground to remove the excess metal 16 and produce the desired profile, after which the surface of the blade is polished.
